Compiling issue - NVCC does not include CUDA include dir

[Grinnz]

I am getting an error in Fedora 20 x86_64 when I try to compile the latest cudaminer or ccminer releases. It cannot find header files in the cuda includes directory (/usr/local/cuda/include, in my case). I work around it by editing the Makefile created by ./configure and adding $(CUDA_CFLAGS) to every nvcc line near the end of the file; this variable is set to "CUDA_CFLAGS = -I/usr/local/cuda/include" earlier in the Makefile but is never used. I don't know enough about autogen to suggest how to fix this in the makefile generation.

For searchability, the error this causes is below:

/usr/local/cuda-5.5/bin/nvcc -g -O2 -Xptxas "-abi=no -v" -arch=compute_10 --maxrregcount=64 --ptxas-options=-v -I./compat/jansson -o salsa_kernel.o -c salsa_kernel.cu
In file included from :0:0:
/usr/include/stdc-predef.h:40:1: fatal error: cuda_runtime.h: No such file or directory
#endif
^

I did the same modification to Makefile.am instead of the generated makefile, and it successfully configured and built.

For future reference this can be solved by setting the symbolic link to /usr/local/cuda:

ln -s /usr/local/cuda-8.0 /usr/local/cuda
